10 Ways Software-Defined Networking Will Change IT, September 30, 2013 When networking professionals converge upon New York for Interop this week, software-defined networking (SDN) stands to establish itself as a major theme throughout session talks and informal conversations. As the industry watches the results of early adopter case studies and hears pundits advocate for this new means of controlling the network fabric, consensus is building for the potential that SDN could be an IT game-changer. Here's how, in the words of experts from around the industry.

"SDN leverages the flow-based paradigm, allowing for user-level policies to be enforced no matter where users physically access the network," said Cohn of Ciena. "Suspicious flows can be rapidly redirected for further security processing, while these processing demands can be relaxed by alleviating the need for all flows in the network to be examined."
